This redirect url is not allowed, you should change the "Allowed domains for the redirection via the module" parameter from the AcyMailing configuration page to "localhost|10.0.0.102|10.0.0.50|10.0.0.29|10.0.0.170|10.0.0.66|10.0.0.101|dev.joomlart.com|demo.joomlart.com|downloads.joomlart.com|220.127.116.11" to allow it or set it to "all" to allow all urls

I can not see the error on your site now.
It’s from the Acymil component, you need to configure the extension as given in the documentation here .
If you do not want to use it, you can disable or remove the component from Extensions > Manage in Joomla admin.
